Field of the Invention The present invention relates to a method for constructing a rehabilitation pipe on the inner surface of an existing drainage pipe such as a sewer pipe, a waterworks pipe or an agricultural waterway. It is related to the measure that enables to partition easily and quickly from the rehabilitation pipe construction direction.

の内面に更生管を施工するようにしている。For example, a profile composed of a strip-shaped member having a long strip shape is spirally wound in an existing pipe to form a rehabilitation pipe, and the mortar is provided between the rehabilitation pipe and the inner surface of the existing pipe. By injecting and solidifying, the rehabilitation pipe is constructed on the inner surface of the existing pipe.

にしている。[0004] Further, tubular objects having a predetermined length are sequentially connected in the existing pipe to form a rehabilitation pipe, and mortar is injected between the rehabilitation pipe and the inner surface of the existing pipe to solidify. By doing so, the rehabilitation pipe is constructed on the inner surface of the existing pipe.

は、その内面と更生管との間にモルタルを延々と注入し
続けなければならず、既設管渠内と更生管との間にモル
タルをもれなく充填させるには無理がある。However, in any of the above-mentioned conventional ones, since mortar is injected from one end side of the rehabilitating pipe after the rehabilitating pipe is manufactured, it can reach hundreds of meters in an agricultural waterway or the like. In a long existing drainage pipe, it is necessary to continue to inject mortar between the inner surface of the drainage pipe and the rehabilitation pipe, and it is impossible to fill the mortar between the existing drainage pipe and the rehabilitation pipe. There is.

管を強固に固着させることが行われている。Therefore, by partitioning the inner surface of a long existing drainage pipe and the rehabilitation pipe at predetermined intervals from the construction direction of the rehabilitation pipe, mortar is injected into each partition to solidify the mortar in the circumferential direction. , The rehabilitation pipe is firmly fixed to the inner surface of the existing pipe.

ルタルを手で詰め込んで間仕切りを作るしかない。However, in the above-mentioned one in which tubular objects are sequentially connected in the existing pipe to form a rehabilitation pipe, when partitioning between the pipe mouth of the tubular product and the inner surface of the existing pipe,
When connecting tubular products one after another, clay-like mortar must be manually packed between the pipe mouth of the tubular product and the inner surface of the existing pipe to create a partition, and in addition, the profile is spiral in the existing pipe. Even in the case of forming a rehabilitating pipe by winding it on, when partitioning the rehabilitating pipe at a midway position in the construction direction after the rehabilitating pipe is manufactured, a hole is partially opened at the partition corresponding position of the rehabilitating pipe corresponding to the partitioning part, There is no choice but to make a partition by manually packing clay-like mortar from the hole.

単かつ迅速に行うことができない。Therefore, in the case where a partition is formed when sequentially connecting tubular products, it is necessary to manually stuff the mortar during the pipe manufacturing work, that is, every time the tubular bodies are connected. In the case where the partition is made after pipe making, it is necessary to manually stuff the mortar from the hole opened at the partition corresponding position of the rehabilitation pipe, and the partition work cannot be performed easily and quickly.

間仕切りするように袋状物を拡径させている。[Means for Solving the Problems] In order to achieve the above-mentioned object, the solution means taken by the present invention is a method for constructing a rehabilitating pipe on the inner surface of an existing drainage pipe, which is located at a midway position in the rehabilitating pipe or at a pipe opening By leaving the contracted bag-shaped object in the circumferential direction between the inner surface of the existing pipe and the existing pipe, by injecting mortar into the bag-shaped object through the mortar injection port and solidifying,
The bag-like material is expanded in diameter so as to partition the rehabilitation pipe and the inner surface of the existing pipe from the construction direction of the rehabilitation pipe.

ルを袋状物に注入するのみで確実な間仕切りが作られ、
間仕切り作業を簡単かつ迅速に行うことが可能となる。According to this specific matter, after the pipe is manufactured after the rehabilitation pipe has been installed on the inner surface of the existing pipe, the mortar injection port of the rehabilitation pipe corresponding to the mortar injection port of the bag-like object left in advance is located at the position corresponding to the mortar injection port. The mortar injection port is led out to the inner surface of the rehabilitation pipe by providing a hole, etc., and the bag is expanded by injecting the mortar into the bag-shaped object through the mortar injection port and solidifying the mortar. The inner surface of the existing conduit will be partitioned from the construction direction of the rehabilitation pipe. For this reason, when connecting tubular products in sequence, the mortar is packed between the pipe mouth of the tubular product and the inner surface of the existing pipe to partition it, or after the rehabilitating pipe is manufactured, it is partially located at the partition corresponding position. There is no need for manual work such as packing mortar from the opened holes and partitioning it, and only after injecting the mortar into the bag-like object from inside the rehabilitating pipe after making the rehabilitating pipe, a reliable partition is created,
The partition work can be performed easily and quickly.

内面と更生管とに密着した状態で固化し、袋状物（網状
体）によって堅牢な間仕切りを作ることが可能となる。Here, as a bag-shaped material, the opening is 0.5 mm.
When a bag-shaped one having a mesh body of up to 5 mm is applied, the injected mortar exudes from the bag and the bag expanded in diameter by the injection of the mortar is the inner surface of the existing pipe. It becomes possible to make a solid partition with a bag-like material (mesh) while solidifying in a state of being in close contact with the rehabilitation pipe.

りを作ることが可能となる。In this case, if the mesh body has an opening of 0.5 mm or less, there is a possibility that a solid partition of the mortar may be formed due to insufficient air bleeding at the time of mortar injection, and a solid partition cannot be made. If the size is 5 mm or more, the mortar may flow out and a reliable partition may not be made.
By defining the partition within a range of 5 mm, it is possible to make a robust and reliable partition.
【００１４】特に、管渠内における更生管施工方法を具

管の施工方向から間仕切りするように拡径させている。That is, a profile made of a long strip-shaped member is spirally wound in an existing pipe to form a rehabilitation pipe, or a tubular product having a predetermined length is formed into the existing pipe. Connected one after another in the culvert to form a rehabilitation pipe,
Before the rehabilitation pipe is constructed, it is left in the existing conduit, and after the rehabilitation pipe is constructed, the mortar injection port is led out from the inner surface of the rehabilitation pipe, and the mortar is injected from this mortar injection port to fill the rehabilitation pipe. The diameter is enlarged so as to partition the interior of the existing pipe from the construction direction of the rehabilitating pipe.

とで、製管機との干渉が容易に回避され、製管機による
製管作業を円滑に行うことが可能となる。By these specific matters, it is possible to form a partition after the rehabilitating pipe is manufactured at an arbitrary position such as a midway position in the construction direction of the rehabilitating pipe or a tube mouth of a tubular object. In particular, in the case of forming a rehabilitation pipe by spirally winding a profile in an existing pipe, by applying a bag-shaped material made of a mesh body, interference with the pipe manufacturing machine can be easily avoided. Thus, it becomes possible to smoothly perform the pipe manufacturing work by the pipe manufacturing machine.
【００１７】特に、袋状物を特定するものとして、以下
の構成が掲げられる。In particular, the following constitutions are given to specify the bag-shaped material.
【００１８】つまり、網状体として、線径が直径０．１
ｍｍ〜３ｍｍの金属繊維よりなるものを適用している。That is, a wire having a diameter of 0.1
A metal fiber having a size of 3 mm to 3 mm is used.
【００１９】この場合、網状体の線径が直径０．１ｍｍ
を下回ると、モルタルの注入圧やモルタルの自重に耐え
得る素材が限定されてコストアップにつながるおそれが
あり、一方、直径３ｍｍを越えると、仕切るべき断面形
状に沿い難くなって確実な間仕切りが作れないおそれが
ある。これにより、網状体としての金属繊維の線径を直
径０．１ｍｍ〜３ｍｍの範囲に規定することで、安価で
かつ確実な間仕切りを作ることが可能となる。In this case, the wire diameter of the mesh is 0.1 mm.
If it is less than 3, the material that can withstand the injection pressure of the mortar and the weight of the mortar may be limited, which may lead to an increase in cost. On the other hand, if the diameter exceeds 3 mm, it will be difficult to follow the sectional shape to be partitioned and a reliable partition can be created. There is a possibility that there is no. Accordingly, by regulating the wire diameter of the metal fiber as the mesh body in the range of the diameter of 0.1 mm to 3 mm, it becomes possible to make an inexpensive and reliable partition.
【００２０】また、拡径時に更生管と既設管渠の内面と
の間の仕切るべき断面形状に即した形状となるように袋
状物を形成した場合には、モルタルの注入によって袋状
物が仕切るべき断面形状に沿って効果的に拡径し、より
確実な間仕切りを作ることが可能となる。When the bag-shaped product is formed so as to have a shape corresponding to the sectional shape to be partitioned between the rehabilitation pipe and the inner surface of the existing pipe when expanding the diameter, the bag-shaped product is formed by pouring mortar. The diameter can be effectively expanded along the sectional shape to be partitioned, and more reliable partitions can be made.

As described above, the aggregate having the peak value of the particle size distribution is mixed with the mortar. In this case, if the particle size of the aggregate is small, the amount of aggregate flowing out of the mesh will be large, resulting in inefficiency. On the other hand, if it is too large, the solidified mortar will have nests and a solid partition. There is a possibility that it will not be possible to make it. Therefore, by defining it as an aggregate that holds the peak value of the particle size distribution at 20% or more of the mesh opening of the reticulated body, it is possible to efficiently make a robust partition.

On the other hand, if the diameter exceeds 3 mm. Since it may be difficult to follow the cross-sectional shape to be partitioned and a reliable partition may not be made, at this point, the wire diameter is defined in the range of 0.1 mm to 3 mm, and more preferably the wire diameter is 0 mm. .3m
It is preferably about m. In addition, the mesh has a mesh of 0.5.
If the thickness is 5 mm or less, the air may not be sufficiently removed when the mortar 7 is injected, and solidified mortar 7 may have nests, so that a solid partition may not be formed. There is a risk that a reliable partition cannot be made, and in this respect, the mesh body is regulated in the range of 0.5 mm to 5 mm, and more preferably 1.7 mm to 1.8 mm. It is suitable.

れる。The mortar 7 contains an aggregate having a peak value of the particle size distribution in 20% or more of the mesh opening of the mesh. In this case, if the particle size of the aggregate is small, the amount of aggregate flowing out from the mesh-like body increases, resulting in inefficiency. On the other hand, if the particle size of the aggregate is too large, the solidified mortar 7 has a nest and is solid. Since a partition may not be formed, an aggregate having a peak value of particle size distribution in 20% or more of the mesh opening amount of the mesh body is preferable in this respect.
As the mortar 7, a mixture of Portland cement with silica sand Nos. 4 and 5 as an aggregate is applied. As a particle size distribution of this aggregate, a minimum diameter of about 0.1 mm, a maximum diameter of about 2 mm, and a peak value of about 0.5 mm are applied. The flow value is preferably about 28 cm. The mortar 7 is
